How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Nut

For Use With: Acetylene, Air, Butane, Diesel Fuel, Compressed Air, Cutting Oil, Fuel Oil, Gasoline, Hydraulic Fluid (Petroleum Base), Kerosene, Mineral Oil, Natural Gas, Helium, Nitrogen, Propane, Soap Solutions
Temperature Range: -10° to 400° F
Tubing: Use with seamless 316Ti or 321 stainless steel
Specifications Met: DIN 3861

Pair these nuts with vibration-resistant compression sleeves and fittings for a strong seal on stainless steel tubing. Made of 316 stainless steel, they have excellent corrosion resistance. All meet DIN 3861, which is an international standard for compression tube fitting specifications.

Vibration-Resistant Compression
Fittings for Stainless Steel Tubing

For Use With: Acetylene, Air, Butane, Compressed Air, Cutting Oil, Diesel Fuel, Fuel Oil, Gasoline, Helium, Hydraulic Fluid (Petroleum Base), Kerosene, Mineral Oil, Natural Gas, Nitrogen, Propane, Soap Solutions
Temperature Range: -10° to 400° F
Tubing: Use with seamless 316Ti or 321 stainless steel
Specifications Met: DIN 3861

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps. However, rubber sleeves can’t withstand temperatures as high as metal ones. To create the strong seal, tighten the included nut. These fittings are made of 316 stainless steel, so they have excellent corrosion resistance. They’re also known as flareless fittings. All meet DIN 3861, which is an international standard for compression tube fitting specifications.

BSPP and metric male threads have a gasket to prevent leaks.

Couplers for High-Pressure Fill Valves

Fill tanks and recharge struts—these couplers join hose to high-pressure fill valves with Schrader threads.

70° elbow couplers are angled to access hard-to-reach valves.

90° elbow couplers have a shut-off valve that lets you control the flow of air by hand. When used with Schrader valves that have a core, the core depressor pin in these couplers press valves open to let air flow in.

Flared couplers meet SAE AS4395, an automotive industry standard for flared fitting dimensions.

Air Flow Check Valves

Push-to-Connect Female
Inlet × Push-to-Connect
Female Outlet

Valves open to allow flow in one direction and close when flow stops or reverses.

Valves with push-to-connect ports are for use with plastic or soft metal tubing. Insert tubing into the port.

Flow coefficient (Cv) is a measurement that indicates how much airflow can pass through a valve.
